zenithal rains

In the Tropics or subtropics, rainy seasons that recur annually or semiannually at about the time that the sun is most nearly overhead (at zenith).

Within a few degrees of the equator, two such periods of heavy rains may occur annually, the equinoctial rains. Farther from the equator, these blend into a single annual summer rainy season.
